I have a set of public computers that I want to remove ALL shutdown, switch users, log off, restart, and lock options. These are public computers that we have and the computers are turned on and off by software we have. I can get everything disabled, except for the logoff button via the group policy management on our domain server.... Is there any way to get rid of that logoff button as well and have nothing?

When you say public do you mean open to any man/woman and his dog that walk in off the street? Why do you want to remove the log off function? Are your users logging in with a default username and password?

Yes, we are a public library, so anyone that comes in can use them. We use Envisionware, a management software that controls timed sessions, reservations, and patrons use their library cards to login through Envisionware. At this point, we really don't need the shutdown options. Envisionware shuts the computers down at night and then another product turns them on in the mornings.

An issue right now is when people want to end their session. Instead of clicking the "end session" button, they often go and shutdown the entire computer or log the computer off. It's difficult for staff to get over to that computer right away to log it back in or turn it back on, and it affects reservations if that computer is reserved.

It would be SO much easier for us to remove the shutdown, log off, and lock features from the computer. If we had to have one option available, the sleep option would probably be the easiest and fastest to get the computer back up. Then if I need to log in as an Administrator, I can go into the server and remove the computer from the policy. It will kind of be two or 3 extra steps, but its not that often I need to get in (everything is done automatically or from the server)..

Does anyone have any tips or suggestions to try and obtain this goal? Or atleast just have the Sleep button available? I need to have something ready by end of day Monday.. I'm hoping to find something better than I have now...Thanks!!

Out of box answer (probably not possible by EoD tomorrow)
1) Thin Client in kiosk mode (don't know app requirements)
2) Windows 8 machine in Kiosk Mode (again with the requirements.
3) Leave the log off button as is, and configure auto-logon for that user.

Alamo, there's a registry key that will disable this button, but it, too, may be affected by the other GPOs in effect, I'll see if I can dig it up, I had used it once before for a Home version workstation that I was stuck with.

Ive already done that regedit. But I also have the "remove and prevent access to the Shut Down, Restart, Sleep, and Hibernate commands. By having them both enabled, the log stll appears (almost like they contradict each other). So that was where I was wondering that maybe it will just be "either, or" and not both options disabled.
